Dingbo Grinding Mill Appication:

The Grindingmill can grind the following non-inflammable and non-explosive materials with the hardness below Scale 9.3 of Moh’s and the moisture content below 6%,such as:

a) Minerals:limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate,etc.

b) Metallurgy materials: manganese ore, iron ore.etc.

c) Chemical materials: active carbon, carbon black,etc.

d) Building materials:glass, ceram, fireproof materials, heat preservation materials,etc.

Working Principle:

Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.

Features and Advantages:

1.the Mill grinding roller pressure on the material under the action of the spring in the high-pressure increase 800 - 1200kg.
2.The Mill on the Mohs hardness of less than 9.3 processing of mineral materials can be crushed.
3.The Mill wide range of product particle size, particle size up to 0.613 mm the thickest (30 mesh) particle size of generally up to 0.033 mm (425 mesh), few materials can reach 0.013 mm the smallest (1,000 head).
